ABSTRACT The invention relates to a device for carrying out a repetitive scan of a sensor element according to predetermined parameters. The sensor element is attached to a permanent magnet with diametrically opposed poles resulting in an open magnetic circuit. A coil is provided around said magnet, through which a current is passed, of predetermined frequency and intensity, where means are provided for enabling the rotation of the magnet and the sensor attached thereto as a result of the interaction of the two magnetic fields. According to a preferred embodiment, the scan is controlled by signals originating from electrooptical sensing means arranged in closed loop with the current which is applied to the coil.
